So my regular lab has given me a Common Swampie over 7 times in a row now :)!!

.... Not even a colored one just common.. Ugh, the lab hates me :P

The thread a few posts down pretty much sums up Zapper V1 http://www.subeta.net/forums/view/661962

Most commonly the zaps are Swampies, Darkonites, and gender changes. But its possible to get other colors like spectrum though.
